To calculate the expected boiling point of lithium fluoride LiF using its experimental melting point and the heat of fusion, we need the following information:1. Experimental melting point of LiF2. Heat of fusion of LiF3. Heat of vaporization of LiFUnfortunately, you have not provided the heat of vaporization of LiF. However, I can help you set up the equation to calculate the boiling point once you have that information.The relationship between the melting point, boiling point, heat of fusion, and heat of vaporization for an ideal substance can be expressed using the Trouton's rule, which states that the entropy of vaporization is approximately constant for most substances. The formula for Trouton's rule is:S_vap = H_vap / T_b 85 J/molKWhere:S_vap is the entropy of vaporizationH_vap is the heat of vaporization in J/mol T_b is the boiling point in Kelvin We can use the melting point and heat of fusion to estimate the entropy of fusion S_fus :S_fus = H_fus / T_mWhere:S_fus is the entropy of fusionH_fus is the heat of fusion in J/mol T_m is the melting point in Kelvin Assuming that the entropy of fusion and entropy of vaporization are proportional, we can write:S_vap / S_fus = H_vap / H_fusNow, we can solve for the heat of vaporization H_vap :H_vap = H_fus * S_vap / S_fus Finally, we can use Trouton's rule to calculate the boiling point T_b :T_b = H_vap / S_vapOnce you have the heat of vaporization of LiF, you can plug it into these equations to calculate the expected boiling point.
